From 62ecc37986414ff98ba863f8f4b8c3fa9c8fb808 Mon Sep 17 00:00:00 2001 From: "RongQing.Li" Date: Thu, 26 Apr 2012 21:01:13 +0000 Subject: [PATCH] drivers/net/oki-semi: Donot recompute IP header checksum If I understand correct, NETIF_F_IP_CSUM only means the hardware will compute the TCP/UDP checksum, IP checksum is always computed in software So as a workround of hardware unable to compute small packages checksum, do not need to compute IP header checksum.
